"(XSDPART17) %a %j %j %j\n%1p contains a leaf (%2p) that is not part of the partition dimension %3p."
*Cause: In the definition of a CONCAT partition template, one of the
partitions was dimensioned by a dimension that is "concat-related"
to a partition dimension, meaning it shares some leaves with the
partition dimension, but it contained some leaves that are not
in the partition dimension.
*Action: Either modify the dimensionality of the partition template to
include a concat dimension that contains all the desired leaves,
or pick a different dimension for the partition.
